From Movie <Vlogumentary>,

Almost all of the vloggers that became famous got on YouTube primarily to connect and communicate. They didn't think of themselves as being entertainers, per se. They were connecting to each other, and there was a great deal of energy behind that.

What does that mean?
What's the energy?
Thank you.

I think "energy" here means something like "enthusiasm" or "drive", JT. These vloggers were motivated by the idea of communicating with each other. They weren't motivated by the idea of being entertainers.
